Embodiment Construction
[0056] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.
[0057] Such as figure 1 As shown, a data writing method provided in the embodiment of the present application includes the following steps:
[0058] S101: Obtain data ciphertext and user identification sent by the client.
[0059] Wherein, the client encrypts the data according to the public key of the pre-configured personal certificate to obtain the data ciphertext. The user ID is used to identify the identity of the current client user. Whenever the client performs data interac...

This application provides data writing, reading, encryption methods and devices, and a data transmission system. The solution includes: when performing data writing, the back-end service forwards the data ciphertext sent by the client to the encryption service, and the encryption service The data ciphertext is decrypted and encrypted twice to obtain the data ciphertext, the encryption service sends the data ciphertext to the back-end service, and the back-end service stores the data ciphertext in the database. When performing data reading, the backend service obtains the data ciphertext according to the access information sent by the client and forwards the data ciphertext to the encryption service. The encryption service decrypts the data ciphertext and encrypts it twice to obtain the data ciphertext. The data ciphertext is sent to the client again through the backend service, and the client decrypts the data ciphertext to obtain the data plaintext. During the transmission process between the database and the client, the back-end service will not receive the plain text of the data, which effectively avoids data leakage and significantly improves the security of data transmission.
Description
technical field [0001] The present application relates to the field of data communication, in particular to a data writing, reading, encryption method and device, and a data transmission system. Background technique [0002] With the rapid development of the Internet, people's life and work are increasingly inseparable from the Internet, and more and more companies have launched their own Internet application products according to their own business. The security of data transmission between the client and the back-end service of the application product is related to the user experience and is an important research object in the development process of the application product. [0003] At present, the existing data transmission between the user and the back-end service generally uses the HTTPS protocol to encrypt and transmit the plaintext data received by the back-end service. Based on the existing data transmission method, the back-end service may have security risks of da...
